<p>I probably should be able to glean the answer from status reports, but I thought I would drop a quick question:</p>
<p>Can I use this yet? =)</p>
<p>In particular, I'm interested in getting some people to start an effort analyzing common crates and trying to get more data about where we spend our time. I've been kind of waiting until we have some sort of self-profile tool available to even think about this, and I'm trying to figure out if it's time to think about it again.</p>

<p>I don't think it's actually been used for <em>"real"</em> performance work, but it should be ready.</p>

<p>We also have a stack-collapse tool for generating flamegraphs with barebones but workable documentation.</p>

<p>I'm currently (well going to bed now) working on displaying diffs of two profilings, so you'd be able to that too within a few days.</p>
